I am using the following:
$chartImage->autoOutput('/statistics/'.$image.'.png');
The problem is that this code outputs the image to the browser. I would prefer it if it saved the image to a file with the directory and name I specified. How do I do this? I was looking at the pChart wiki, and its very confusing with all this pCache stuff. I don't have a need for any caching or anything like that... I just want to save the image.
Try to use:
$chartImage->render("image_name.png");
It worked for me in 1.x, don't know about 2.x - did not used it.
